Table 7
Inom is the measured current when the output from the current sensor is 1V.
Pnom and Snom are the active and apparent powers for V = 1,000 V, I = Inom, and PF = 1.
Qnom is the reactive power for V = 1,000 V, I = Inom, and sin
ϕ
= 1.
The intrinsic uncertainty of the current inputs is specified for an isolated voltage input of 1V, corresponding to Inom. The intrinsic
uncertainty of the current sensor used must be added to it to determine the total uncertainty of the measurement system. With
the AmpFlex
®
and MiniFlex
®
current sensors, the intrinsic uncertainty given in Table 21 must be used.
If there is no current sensor, the intrinsic uncertainty on the neutral current is the sum of the intrinsic uncertainties on I1, I2, and I3.

Inom is the measured current when the output from the current sensor is 1V.
Pnom is the active power for V = 600 V, I = Inom, and PF = 1.

If there is no current sensor, the intrinsic uncertainty on the neutral current is the sum of the intrinsic uncertainties on I1, I2, and I3.
With the AmpFlex

current sensors, the maximum current is limited to 60% Inom at 50/60Hz.
